Question

Calculate angle between two lines using coordinates

Answer 1

Using coordinates find the slope of the two lines.
Then put it in the formula of
=> tan theta = (m1-m2)/(1-m1m2)

Answer 2

➡HERE IS YOUR ANSWER⬇

Let us consider two lines :

y = mx + c .....(i)

and

y = m'x + c' .....(ii)

If θ be the angle between lines (i) and (ii), then

tan θ = (m - m')/(1 + mm')

■] Slope Formula :

If any two points (a,b) and (c,d) are given, then the slope of the line joining these two points is

m = (d-c)/(c-a)
